Application filed June 3, 1921.

To all I'wiiom t may concern i Be` it lznownthat I, .BURTON WV. FIL/irren, a citizen of the United States, residing at Brooklyn, in the county @it Kings `and State oit Neu1 York, have invented certain neuT and useful Improvements in Deinountable Rims, oi which the following is a specification.

This in vention 'relates to rims especially adapted tor use on the Wheels ot motor vehicles. i

An important object ot this invention is to provide a sectional rim which utilizes the pressure ot the tire carried thereby as a means for holding the several sections together and for preventing the sections trom rattling.

A further object of the invention is to provide `a sectional rim `which may be quickly attached t0 or removed from a tire Without the necessity of employing a number of tools or Without excessive effort ou the part of the operator.

.A further object is to provide a rim oit the class described Which is efficient, durable in use and cheap to manufacture.

Other objects and advantages @t the invention Will be apparent during the course o1 the following description.

In the accompanying drawings forming a part ot this application and in which lilre numerals are employed to designate like parts throughout the same.

Figure 1 is a side elevation ot the iniproved rim equipped with a tire.

Figure 2 is a the rim.

Figure 3 is an'end view oit one ot the sections of the rim, the view being taken on line 3-3 of Figure l.

Figure 4t is a view taken on line lmet of Figure 1, the connecting means for the rim sections being shown in section and one of the rim sections being shovvn in end elevation.

Figure 5 is a sectional view through the rim, the parts being shown in the position they occupy preparatory to attaching the same to a tire.

.Figure 10 is fragmentary perspective ol' one ot the riin sections.

In the drawing the numeral 10 generally designates the rim which consists ot arcuate sections 11 and 12 which are ol a greater length than sections 13 and let. The several sections of the rim are adapted to be detachably connected and held in that position principally by means oit the air pressure contained in a tire 15 having beads 1G confined between the side tlanges 1T and pressed laterally by means ot the prem sure Within the tube 18. As illustrated in Figure 3, the usual tlap 20 is arranged about the rim and has its edge portions` engaged 'with the beads 16 so that the air pressure will be uniformly applied to the side Hannes 17 whereby the several sections of the rim are securely though detachably held in position.

The section 12 et the rim provided at one end With a transversely extending tongue 22 terminating adjacent the flanges 17 and adapted to be received Within a `transversely extending groove in the adjacent end. of the section 11. so as to hold the sections 1l and 12 against lateral movement with relation to each other. The trans versely eiiztending tongue which is arranged betiveen the inner and outer sides of the section 12 is tapered to u. point and the groove which receives the same is ot a similar formation.

The sections 13 and 11i are providi-id at their' ends with tongues and grooves and Qt respectively cooperate with each other and with similaitongues and grooves `in the adjacent ends ot' the sectionsll and 12 in providing a connection between the see- Itions ot the rim. lflith reterence to liigures l and 1() .it will loe noted that the grooves or recesses Ql are arranged in paire` as are the tongues which are received Wit-hin the same. The recesses 24; ot each pair are arranged on opposite sides of channels 26 termed in the sections 13 and 14t and the ad jacent portions et the sections 11 and 12 tor the reception ot a locking strip designated by the Vnumeral 28. The locking strip 28 when received Within the channels 26 has its face flush Vwith the inner face of the rims@ as not to interfere with the application of the rim to a Wheel. Further,l the side walls of the channels 26 hold the Y locking strip 28 against lateral movement.

One end of the channel 26 formed in the section 11 is provided With an overhangrng portion 30 Which defines a cavity to receive the adjacent end of the locking strip 28Y whereby to hold that end of the strip in position when the other end is held Within the channel 26 in the section 12 by means 32 so that a screwdriver vmay be engaged with the latch for the purpose of rotating the same. The ends of the locking strip 28 flatlyengage the ends ot the channels 26 and one end of the locking strip is bevelled as indicated at 35 so as to flatly contact with the inclined bottom Wall 36 of the cavity `formed by the overhanging portion Y 30. Then it is desired to remove the locking strip 28 a screwdriver may be inserted into a notch 38 formed in one side of the strip.

In the form or" the invention illustrated in Figure 7, the channel 26 is formed by pressing or stamping the rim in such a manner that a reinforcing rib 39 is formed on the outer side of the rim, which rib is located between the beads of the tire.

In the form of the 'invention illustrated in Figure 9 the rim section designated by the numeral 4() is adapted for application to a slightly different type otvvheel felly and is provided vwith a pair of spaced ribs 41 which define a channel 42 for the reception of a locking strip.

ln applying the rim, the sections 11 and 12 are engaged 'with the tire as illustrated in Figure 1 and the short sections 13 and Mare now larranged in the manner illustrated in Figure `5. lVith the parts thus positioned the operator may step on the meeting ends of the sections 13 and 14 so as to cause the rim to assume a circular formation. The locking strip 28 is nonv inserted into 'the aligned channels 26, one

vend ot the strip being confined within the cavity in the section 11 and the other end being securely held by the latch 32.

In use, the pressure of the tire is utilized to hold the several sections together in cooperation With the locking strip 28. Should the tire become deflated the same Will reiain on the rim since the beads are securely confined between the fianges 17.

I claim 1. A sectional rim comprising a pair of long arcuate sections and a pair of short arcuate sections cooperating with the long sections in forming a circle, the ends of the sections being formed With interlocking tongues and grooves, a locking strip applied to the inner sides of the short sections and overlapping the adjacent portions of the long sections, and means carried by the long sections for securing the locking strip in position.

2. A sectional rim comprising pairs of long and short sections having their ends formed with interlocking tongues and grooves detachably connecting the sections, said short sections and the adjacent portions ot said long sections being formed with aligned channels, a locking strip received Within said channels and having one of its ends beveled, the channel in one ot said long sections heilig iorined With a cavity receiving the beveled end of said locking strip and having an inclined bottom Wall snugly contacting With the beveled portion of said locking strip, and a latch pivotally carried by the other long section and engagingthe adjacent end ot said strip.

3. A sectional rim comprising long and short sections having their ends formed with interlocking tongues and grooves detachably connecting the sections, said short sections and the end portions of said long` sections being provided with aligned channels, a locking strip snugly fitted within said channels and having its ends contacting with the ends ot the channels formed in said long sections, a pivoted latchplate connected to one of said long sections and engaging the adjacent end of' said locking strip to hold the same Within said channels, the inner face oi said strip being flush with the inner faces ot said sections.

et. sectional rim comprising long and short arcuate sections having their ends formed With'means whereby the same may he detachably connected. said short sections and said long sections being provided with aligned channels, a locking strip received Within said channels and having its inner face fiush with the inner faces of said sections` and means whereby the locking strip may be confined Within said channels.

In testimony whereof, I have affixed my signature in the presence of two Witnesses.
